The BenQ G2222HDL is a 21.5-inch Full HD LED monitor, and the D-SUB refers to the VGA (Video Graphics Array) port used to connect the monitor to a computer. The term "Windows driver" in this context is a bit of a misnomer because, unlike many hardware devices such as printers or scanners, monitors typically do not require specific drivers to function on modern operating systems like Windows.
In most cases, a standard VGA or D-SUB connection, like the one used by the BenQ G2222HDL, is automatically recognized by Windows, and the monitor will work out of the box using the default generic monitor driver that comes with Windows. However, BenQ may provide drivers or software for advanced display settings, color calibration, or specific features for the monitor.
